    Subject[PATCH AUTOSEL 5.15 20/37] ARM: versatile: Add missing of_node_put in dcscb_init
    Date
    From: Peng Wu <wupeng58@huawei.com>

    [ Upstream commit 23b44f9c649bbef10b45fa33080cd8b4166800ae ]

    The device_node pointer is returned by of_find_compatible_node
    with refcount incremented. We should use of_node_put() to avoid
    the refcount leak.
